WM. CLOUGH, OF MADISQN INDIANA.

LUBRICATOR FOR 'RAILROAD-AXLES.

Specification of Letters Batent No. 19,7 50, dated March 30, 1858.

To all whom it may concern:

Be it known that I, WILLIAM CLoUcH, of Madison, in the county of- J eiferson and State of Indiana, have invented an Improved Lubricator for Railroad-Axles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1, represents a longitudinal section of the oil box and bearing and side view of a journal, and exhibits the application of iny improved lubricator. Fig. 2, represents a transverse section of the box, and end view of the journal and exhibits the lubricator in two positions.

Similar letters of reference indicate like parts in both figures.

This invention consists in a hand attached to a sleeve or hub which is fitted to work on a spindle within the oil-box and which has also attached, to it a slotted or jointed arm that is connected with an eccentric wrist at the end of the axle, the said arm, hand, and sleeve being so arranged that by the rotary motion of the wrist with the axle the hand is caused to receive a swinging mot-ion which alternately dips it into the oil in the oil-box to take up a small quantity of oil or grease and lifts it up into contact with the journal to deposit the oil so taken up or 'a portion of it upon the journal.

The invention consists also in making the said slotted arm, sleeve and hand of a single piece of wire in such a manner that the sleeve constitutes a spring which enables the hand to rest for an instant against the journal, to insure the deposit of oil thereon, and serves to obviate any liability to breakage of the arm or hand by the concussions produced by their very rapid mot-ion.

To enable others to make and use my invention, I will proceed to describe its construction and operation.

A is the oil-box; B, is the journal, and C, is the brass or bearing.

D, is the spindle upon which the sleeve of the lubricator works screwed at one end, which passes the shell of the box A, and is secured thereto by two nuts a, a. 1

E, is the oiling hand; F, is the sleeve to which it is attached, and G, is the slotted arm attached to the said sleeve, all formed of a single piece of wire, the sleeve being made by coiling the wire in such a manner as to constitute a spring.

I), is the eccentric wrist which imparts motion to the lubricator, said wrist being screwed into the end of the axle. This wrist as it rotates worksin the slot of the arm G, and thus gives a-vibratory motion to the said arm, which causes the hand E, to dip into the oil or grease as shown in black outline in Fig. 2, and then rise in contact with the journal as shown in red outline in the same figure, to deposit it thereon once during every revolution of the axle. By setting the hand E and arm G, at such an angle to each other that the hand touches the journal a little before the arm is moved by the wrist b, to its greatest distance from the axis of the journal the hand is caused to be retained temporarily, though for an imperceptible moment, against the journal and thus to have a better opportunity of depositing the oil or grease upon it, which action could not be permitted without the elasticity of either the arm, hand, or sleeve, but is provided for by the construction of the sleeve of the same piece of-wire as the arm and hand. This construction also provides against the breakage of the arm and hand, by the hand striking the journal, which it must do with great velocity, owing to the rapid revolution of the journal, and compensates for wear. Besides those advantages of the above construction, it is the cheapest that can be adopted, the lubricator with all its appendages costing less than five cents, and requiring but about ten minutes to apply it to any of the oil-boxes now generally used.

If desired, the hand E, can be formed to extend the whole length of the journal; and the arm G can be extended downward sulficiently to dip into the oil and oil the face a or end of the journal; but these modifications will be hardly necessary.

The arm G, instead of being slotted, can have a joint to provide for the movement of the wrist toward and from the spindle D, which joint will be equivalent to the slot.

I do not claim the use of an arm deriving such a motion from the axle as to dip into the oil or grease and deposit upon thejournal at every revolution thereof; but

What I claim as my invention and desire the purpose set forth.

5 to secure by Letters Patent, is:

1. The combination of the oiling finger E, sleeve or hub F, slotted arm G, and Wrist b in the manner and for the purpose described.

2. And I also claim making the oiling finger E sleeve F and slotted arm G from the 10 same piece of Wire, in the manner and for J WM. CLOUGH. Witnesses:
